Airbag suspension

I'm thinking of doing a SOA conversion on my CJ7 and i was thinking that i could run air bags on the suspension to make it flex when off road but firm when on road, are there any draw backs to air bags or this idea?

The main drawbacks are the price, added body roll, and something rupturing the airbag itself. There are some writeups on airbag suspension for jeeps on the internet and also in some of the latest off road magazines. In the latest JP or 4-wheeler there was a guy running it on a jeep and punctured one of them, but he just added a coil back in until he finished the trail.

This site has a good system that eliminates body roll and automatically adjusts on the road, but if you're on the trails alot, you would probably want one that was independantly controlled at all 4 corners. If you've got the $ then it's not a bad idea.

Now for the advantages

the airbag system is designed for a TJ... you could design a link suspension to run it, but why not just run coilovers (expensive) or 1/4 elliptic springs (cheap) in the rear if you're going to bother with a linked suspension? sticking an airbag between your frame and leaf spring isn't going to improve your articulation any...

personally if you want more flex, SOA your front leafs and do a 4 link with 1/4 elliptical springs... avalanche has an overpriced kit for this at

or you can piece together rodends, spuds, jam nuts and some 1.5 .250 wall DOM, brackets and do it yourself... you need welding and fabrication knowledge
